Question

4)Calcule as potências:
a(+3)²
b(+5)³
c(+7)²
d(-11)²
e(-5)³
f(-9)°
g(+6)¹
h(+31)°
o(-9)¹
m(+2)³​

Answer 1

obs;

Todo número elevado

a zero é igual há 1

$\Box \ \ \boxed{\begin{array}{l}\sf a)\\(+3)^2 \ \ = \ 3.3 \ = \ 9 \end{array}}$

$\Box \ \ \boxed{\begin{array}{l}\sf b)\\(+5)^3=5.5.5=125 \end{array}}$

$\Box \ \ \boxed{\begin{array}{l}\sf c)\\(+7)^2=7.7=49 \end{array}}$

$\Box \ \ \boxed{\begin{array}{l}\sf d)\\(-11)^2=-11.-11=121 \end{array}}$

$\Box \ \ \boxed{\begin{array}{l}\sf e)\\(-5)^3=-5.-5.-5=-125 \end{array}}$

$\Box \ \ \boxed{\begin{array}{l}\sf f)\\(-9)^0=1 \end{array}}$

$\Box \ \ \boxed{\begin{array}{l}\sf g)\\(+6)^1=6 \end{array}}$

$\Box \ \ \boxed{\begin{array}{l}\sf h)\\(+31)^0=1 \end{array}}$

$\Box \ \ \boxed{\begin{array}{l}\sf o)\\(-9)^1=-9 \end{array}}$

$\Box \ \ \boxed{\begin{array}{l}\sf m)\\(+2)^3=2.2.2=8 \end{array}}$

Respostas Corretas;

a) = 9

b) = 125

c) = 49

d) = 121

e) = -125

f) = 1

g) = 6

h) = 1

o) = -9

m) = 8
